The package for the ninja build system failed to compile. Seems to be the "Apple M1" ghost haunting us again. But now on such a central package... a build system package! I bet it will be sorted out quickly.

Seems similar to this: fonttools/ttfautohint-py#7

[simoncozens]

Is this on Apple Silicon, @davelab6?

I don’t feel like we should be making people build meson and ninja anyway. There should be binary wheels for ots.

[simoncozens]

Ah, OK, so there are, but not for M1. There's already an open discussion about whether to ditch ots-python and move to pyots, but the same issue applies. (Although admittedly pyots is further down the road of GitHub actions.) I think there are some good reasons why it would be good to move to pyots and send them a PR to get M1 working.

[anthrotype]

according to https://github.com/scikit-build/ninja-python-distributions/releases/tag/1.10.2, there are now universal2 wheels for ninja on PyPI. Can someone try again and confirm that it works now from an M1 mac?

[anthrotype]

@simoncozens @eliheuer I updated the ots-python CI to build universal2 wheels for the new M1 macs.
Can anybody give them a go and confirm they work?
You can download the "artifact.zip" file from: https://github.com/googlefonts/ots-python/suites/3493977623/artifacts/83204297 (which contains all the built wheels, including the universal2 one).

You pip install local/path/to/downloaded/opentype-sanitizer-*.whl in a venv, and then try to run the test suite or simple take a font and run it through python -m ots INPUT_FONT and confirm it doesn't crash when run on an Apple M1 chip
I'll cut a release soon.

[anthrotype]

you should be able to pip install now => https://pypi.org/project/opentype-sanitizer/8.1.4.post3/#files

Do let me know if there are other dependencies of gftools that need to be rebuilt for Apple Silicon

[eliheuer]

Thank you @anthrotype!

I did some testing on my M1 mac (Big Sur 11.2, Python 3.9.6) today.

• pip install ninja works! Successfully installed ninja-1.10.2
• I downloaded "artifact.zip" file from: https://github.com/googlefonts/ots-python/suites/3493977623/artifacts/83204297
• Tried: pip install opentype_sanitizer-8.1.4.post3.dev13+gf97b12c-py2.py3-none-macosx_10_9_universal2.whl
• It worked! Successfully installed opentype-sanitizer-8.1.4.post3.dev13+gf97b12c
• Tried: python -m ots Font.ttf
• It worked! File sanitized successfully!
• Tried: pip install opentype-sanitizer==8.1.4.post3
• It worked! Successfully installed opentype-sanitizer-8.1.4.post3

Thanks again! A Mac Mini M1 is my main computer for working with Glyphs and I have been switching to an old Mac laptop every time I need to run Google Fonts CLI tools, that was a huge pain.

[anthrotype]

@eliheuer thanks for checking!
@felipesanches should we now close this issue?

[m4rc1e]

Thanks everyone!

[felipesanches]

thanks!
